Theodor Boveri

Theodor Boveri (12 October 1862-15 October 1915) was a German biologist who correctly hypothesized the link between cell abnormalities and cancer, and who worked with Walter Sutton to apply Mendelian ideas to chromosomes at the cellular level of organisms.

Biography
Theodor Boveri was born in Bamberg, Bavaria in 1862, and he became a biologist. His work with sea urchins showed that it was necessary to have all chromosomes present in order for proper embryonic development to take place, appplying Mendelian laws to chromosomes at the cellular level, just as his American counterpart Walter Sutton was doing. In 1902, he also reasoned that a cancerous tumor originated with an abnormal cell, which caused cells to divide uncontrollably. In 1915, Thomas Hunt Morgan discovered that he was correct. He died in Wurzburg in 1915 at the age of 53.
